Abstract

Device for the continuous homogenisation of a mixt. of solid and/or liquid prods. comprising at least one means for carrying these prods. This is formed by a helicoidal element (1) rotated by a motor (3), which surrounds at least one U-shaped internal section (2). The curved part (12) of the section is at the opposite end of the device to the exit from the helicoidal element and the legs (20) of the U are fixed to the internal faces of the spiral. Continuous homogenisation process for a mixt. of solid and/or liquid prods. characterised in that the mixing and beating of the prods. is done simultaneously by means of a device as described above and below. The distance between the legs of the U section is effectively equivalent to the internal dia. of the helicoidal element. The curved part of the U section extends outside the helicoidal element beyond the plane of the end spiral. The legs of the section are soldered to the inside of the spiral. The helicoidal element can enclose several internal sections arranged one behind another at the same level, in the same or different diametral planes. USE - Continuous mixing device which prevents the agglomeration of more compact prods. at the periphery, retaining only the more fluid prods. at the centre. This device therefore provides complete homogenisation of the mixt. without any need for extra machinery.

Description

DISPOSITIF ET PROCEDE D'HOMOGENEISATION D'UN
MELANGE DE PRODUITS.DEVICE AND METHOD FOR HOMOGENEIZING A
MIXTURE OF PRODUCTS.

La présente invention concerne un dispositif et un procédé pour l'homogénéisation d'un mélange de produits solides et/ou liquides. The present invention relates to a device and a method for the homogenization of a mixture of solid and / or liquid products.

Plus précisément, l'invention porte sur un perfectionnement aux dispositifs de mélange comprenant au moins un moyen d'entraînement des produits constitué d'un élément hélicoïdal entraîné en rotation par un organe moteur. More specifically, the invention relates to an improvement in mixing devices comprising at least one product drive means consisting of a helical element driven in rotation by a motor member.

En effet, dans ces dispositifs, les produits les plus compacts ont tendance à s'agglomérer à la périphérie de l'élément hélicoïdal tandis que les produits les plus fluides sont transférés par le centre. In fact, in these devices, the most compact products tend to agglomerate at the periphery of the helical element while the most fluid products are transferred through the center.

Dans ces conditions, le mélange n'est pas homogène et il est alors nécessaire de prévoir des organes ralentisseurs du débit de sortie constitués par exemple d'un pointeau réglable venant obturer de façon sélective l'extrémité de sortie de l'élément hélicoïdal. Under these conditions, the mixture is not homogeneous and it is then necessary to provide organs for retarding the outlet flow rate constituted for example by an adjustable needle selectively closing the outlet end of the helical element.

I1 est même parfois nécessaire d'installer des équipements complémentaires en aval pour homogénéiser et parfaire le mélange. It is even sometimes necessary to install additional equipment downstream to homogenize and perfect the mixture.

La présente invention a pour but de résoudre les problèmes techniques précédents de manière satisfaisante. The present invention aims to solve the above technical problems satisfactorily.

Ce but est atteint au moyen d'un dispositif pour l'homogénéisation continue d'un mélange de produits solides et/ou liquides comprenant au moins un moyen d'entraînement de produits, constitué d'un élément hélicoïdal entraîné en rotation par un organe moteur, caractérisé en ce que ledit élément hélicoïdal renferme au moins un profilé interne en U dont la partie coudée est disposée du côté de l'extrémité de sortie dudit élément hélicoïdal et les branches dudit profilé sont fixées aux faces internes des spires dudit élément. This object is achieved by means of a device for the continuous homogenization of a mixture of solid and / or liquid products comprising at least one product drive means, consisting of a helical element driven in rotation by a motor member. , characterized in that said helical element contains at least one internal U-shaped profile, the bent part of which is disposed on the side of the outlet end of said helical element and the branches of said profile are fixed to the internal faces of the turns of said element.

Selon une caractéristique avantageuse, l'écartement des branches du profilé en U correspond sensiblement au diamètre interne de l'élément hélicoidal.  According to an advantageous characteristic, the spacing of the branches of the U-shaped profile corresponds substantially to the internal diameter of the helical element.

Selon une autre caractéristique, la partie coudée du profilé en
U s'étend vers l'extérieur de l'élément hélicoïdal au-delà du plan de la spire d'extrémité.According to another characteristic, the bent part of the profile in
U extends towards the outside of the helical element beyond the plane of the end turn.

Selon encore une autre caractéristique, les branches du profilé sont soudées aux faces internes des spires.  According to yet another characteristic, the branches of the profile are welded to the internal faces of the turns.

Un autre objet de l'invention est un procédé d'homogénéisation continue d'un mélange de produits solides et/ou liquides, caractérisé en ce qu'on effectue simultanément le mélange et le battage des produits au moyen du dispositif précédent. Another object of the invention is a process for continuous homogenization of a mixture of solid and / or liquid products, characterized in that the mixing and threshing of the products is carried out simultaneously by means of the preceding device.

Le dispositif de l'invention permet d'obtenir à la fois un mélange homogène et un effet de battage des produits en permettant ainsi de diminuer le travail des équipements placés en aval. The device of the invention makes it possible to obtain both a homogeneous mixture and a threshing effect of the products, thereby making it possible to reduce the work of the equipment placed downstream.

De plus, les déformations de l'élément hélicoïdal sont évitées par la présence du profilé interne qui joue le rôle d'armature sans gêner la rotation dudit élément. In addition, the deformations of the helical element are avoided by the presence of the internal profile which acts as a frame without hampering the rotation of said element.

L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée du dessin sur lequel la figure 1 représente une vue partielle en perspective du dispositif de l'invention. The invention will be better understood on reading the description which follows, accompanied by the drawing in which FIG. 1 represents a partial perspective view of the device of the invention.

La figure 1 représente le moyen d'entraînement du dispositif de l'invention constitué d'un élément hélicoïdal 1 entraîné en rotation autour de l'axe longitudinal x par un organe moteur 3. FIG. 1 represents the drive means of the device of the invention consisting of a helical element 1 driven in rotation about the longitudinal axis x by a motor member 3.

L'élément hélicoïdal 1 renferme au moins un profilé interne 2 en U. Sur la figure 1, un seul profilé 2 est représenté mais on peut très bien concevoir d'autres modes de réalisation dans lesquels d'autres profilés internes en U sont disposés soit derrière le profilé 2 en des emplacements prédéterminés, soit au même niveau, suivant le même plan diamétral ou des plans diamétraux d'orientation différentes. The helical element 1 contains at least one internal U-shaped profile 2. In FIG. 1, only one profile 2 is shown, but it is very possible to imagine other embodiments in which other internal U-shaped profiles are arranged either behind the profile 2 in predetermined locations, either at the same level, along the same diametral plane or diametrical planes of different orientation.

La partie coudée 12 du profilé 2 est disposée du côté de l'extrémité de sortie 1 1 de l'élément hélicoïdal 1 en s'étendant vers l'extérieur au-delà du plan de la spire d'extrémité. The bent portion 12 of the profile 2 is disposed on the side of the outlet end 1 1 of the helical element 1 extending outwards beyond the plane of the end turn.

Les branches 20 du profilé 2 sont insérées à l'intérieur de l'élément hélicoïdal 1 en étant fixées par exemple par soudure et au moins partiellement sur les faces internes des spires 10 dudit élément. The branches 20 of the profile 2 are inserted inside the helical element 1 while being fixed for example by welding and at least partially on the internal faces of the turns 10 of said element.

Sur la figure 1, l'écartement des branches 20 du profilé 2 correspond donc sensiblement au diamètre interne de l'élément hélicoïdal 1. In FIG. 1, the spacing of the branches 20 of the profile 2 therefore corresponds substantially to the internal diameter of the helical element 1.

A l'extrémité de sortie de l'élément hélicoïdal 1, les produits déplacés au niveau de la partie centrale sont retenus par la partie coudée 12 du profilé 2 en U puis repoussés latéralement où ils sont battus par les branches 20. On réalise ainsi l'homogénéisation des produits en effectuant simultanément leur mélange et leur battage. At the outlet end of the helical element 1, the products displaced at the level of the central part are retained by the bent part 12 of the U-shaped profile 2 and then pushed aside laterally where they are beaten by the branches 20. This produces l homogenization of the products by simultaneously mixing and threshing.

Selon la nature des produits, on pourra concevoir des modes de réalisation variés dans lesquels les dimensions et la position relatives du profilé 2 et de l'élément hélicoïdal 1 sont ajustées pour optimiser leur homogénéisation.  Depending on the nature of the products, it will be possible to design various embodiments in which the dimensions and the relative position of the profile 2 and of the helical element 1 are adjusted to optimize their homogenization.
